I will not agree to this, they will take as much lee way as much as you give them, who asked you to go to their office, it is the sellers duty to see that the item is delivered to your doorstep and anyway the seller has paid them for doorstep service so they have to deliver the item at your door. If somebody will ask you to jump in a well will you jump, use your common sense.
You should have asked them politely and firmly to deliver at your door or return the item back to the seller. They would have 100% delivered it to you.
